Spring RTS Engine

Used to be that if I had a group of units, say 10 FARKS and 1 adv builder, I could select them all at once, issue a build order and they would all assist the one builder

now only the builder obeys and the rest just stand where they were instead of assisting

which UI has to be enabled to bring that back?

first time i hear about that

What units are you using?
The rezbots ie "Rector" can not build anything or assist since some time. They can only resurect units now.
